DC-1520 15V 2a AC-DC 5.5mm x 2.5mm power supply adaptor quality charger UK

Product Information

I am using unsupported plugs and cables, which seems more likely. However, both chargers are rated for above 65W, which is why I don't understand why the don't work. Futhermore, the USB C cable is rated for 100W. That being said, I don’t recommend fudging the margin under the assumption that you can do the equivalent of driving 5 MPH over the speed limit with your electronic devices. The margin is there for a reason, and the more complicated the device, the more potential for something to go wrong. But next week I have a device coming that also has a US 2 pin plug but is rated much lower than a set of hair straighteners, rated at 5v/2a.

Next, you want to look at your device for the DC input. You’ll usually see at least the voltage near the DC plug receptacle. But you also want to make sure the current matches, too. You might find both the voltage and the current elsewhere on the device, on the bottom or inside a battery compartment cover, or in the manual. Again, look for the polarity by either noting a + or – symbol or the polarity diagram. I since found out that as well as having a plug that converted US to UK, it should also have had voltage step down capability, so we bought one of the right type and all was well. I'm starting to think that Valve are trolling me into only buying their official chargers, which I don't want to do. Most are either a brand we never heard of or just a generic “ac adapter” where you’d otherwise see a brand.

A Very Brief Introduction to Electrical Terminology

If you multiply the voltage by the current, you get the wattage. But the number of watts alone won’t tell you if the adapter is right for your device. Reading an AC/DC Adapter Label

But i did decide to give it a try because when i opened the plastic box of the Creative AC Adaptor, i found that it had only a stepdown transformer inside and i concluded that the AC TO DC Converter circuit had to be located inside the Woofer box to which the AC 11.5V 1600mA was to be fed. I have some universal converters that work fine with Chinese 2 pin ac adapters of the same rating but know that China uses a 220V, 50HZ system, whereas the US is 120V/60HZ. You go to the store for a replacement supply, and they have two kinds of 20 volt power supplies, a 65 Watt and a 90 Watt. (Which is actually the case at my local computer shop, NCIX, except they’re 19 volts. But 20 makes for simpler math.) Which one should you choose? One minute, I get a slow charger warning. The next minute, it stays stable, not loosing charge, but not gaining charge either.

In practice solid chargers support multiple Voltages with Amps that make sense, the device its connected to simply tells the charger which it accepts. Remember: the input of the device should be the same as the output of the adapter. This includes polarity. If the device has a DC input of +12V / 5.4A, get an adapter with a DC output of +12V / 5.4A. If you have a universal adapter, ensure it has the proper current rating and choose the correct voltage and polarity. Fudging It: What Happens if You Use the Wrong Adapter?

In the past I experienced the same as you with 99% of universal or “multi-voltage” power adapters to be cheaply made with little to no documentation or practical information about how to use them with whatever electronic device you are trying to power until I found the ProTechTrader ones. They have instructions that are in a way similar to the post explaining the basic usage and how to properly match the voltage and amperage to the current needed by the device. They also had a nearly identical disclaimer as you mentioned as well as reversible polarity tips which I haven’t seen available on most of the others floating around. I have to see if I can find a link to the manual online somewhere to show you what I mean, but this post is excellent and goes into even more detail anyway. I got a few of the 30w ones here: Your article starts out describing my dilemma almost to a ‘T,’ then never does really answer the question, how do I know which adapter will work with which device. But what if you accidentally (or purposefully) use the wrong adapter? In some cases, the plug won’t fit. But there are many instances where an incompatible power adapter will plug into your device. Here’s what you can expect in each scenario: For example, the Samsung Galaxy Note 3’s power is 10.6W (5.3V×2A) and a powerbank of two port which the output is the same but the current is different. The output one is 5V/1A and the other one is 5V/2.1A. Something to keep in mind when dealing with chargers and electricity in general is that W stands for Watts, wich is nothing more then the Volts multiplied by the Amps.

Fudging It: What Happens if You Use the Wrong Adapter?

My original AC Adapter for my Sega Genesis model 2 (10V 0.85A DC), so I found among my junk box (yeah, we all have one, right? Lol) a replacement (9V 0.2A DC). That said and considering the info perfectly explained on this post, I want to know if this new adaptor will harm my console? To complete the example, suppose they also offered a 200 watt power supply. (I don’t know if such things exist, but feel an urge for completeness in my story.) That would be like towing your boat behind a locomotive – it won’t hurt anything, but you’re wasting money buying an excessive amount of power that you will never use. If the manufacturer gave you a 70 watt power supply with your device, you can safely assume that device shouldn’t need more power than that.
